A method of after-care in relation to patients with at least one electromedical implant. The antenna mount can be installed by inserting it into an opening in the casing of a device and rotating the antenna mount until it abuts a stop stud. An interpolation offset is then derived, comprising a deviation between locations of the interpolated and sampled local maxima or minima of the function. The condition part includes at least one positional condition which defines the relative position of at least two electronic devices. Then, this determined parameter is utilized, while analyzing the measured data obtained with the second measurements enabling the determination of the profile of the structure.
